Abstract:
To study a practical approach of second order displacements for huge steel frames, an equivalent model for the huge steel frame structure is established according to continuous concept and stiffness equivalent principle. Considering second order effect of the structures, a practical model of second order analysis is proposed, and the stiffness equation of second order analysis for the model is established. The feasibility and reliability of the methods are verified by practical example. The results show that the effects of second structures and equivalent joint-panel shear deformation on global structural deflection can be neglected and iteration can be avoided for second order analysis. The calculation is very quick and convenient and analysis precision can meet the demands in practical design.
